I just installed 2g of RAM in the #2 slots (2 1g PC3200 400mhz 2.6v sticks) in my PPC dual 2.0 G5. Now the display isn't coming on. It is getting power because the blue indicator light comes on during startup. I removed the 2g leaving only the original 512 and still getting the same result. Has anyone had a similar problem? Could i have inadvertantly knocked the video card loose during installation?
